Do not set lo.disable_ipv6=0 by default

Forcing lo.disable_ipv6=0 in tripleo-ansible may result in such
value being placed in /etc/sysctl.d/99-tripleo.conf *before*
net.ipv6.conf.all.disable_ipv6 = 1, thus effectively being ignored.

See rhbz#1841522 for an example of a side effect of this, where
'KernelDisableIPv6: 1' results in epmd/rabbitmq being unable to start.
